I keep hearing of "90 Amp chargers" but, just to be clear, the CS-90 model that Sun Country is offering charges the vehicle at around 70 Amps. It is the breaker in the hydro panel that needs to be 90 Amps.

Wouldn't the CS-100 model (as shown in the brochure) make more sense for Model S owners? If you're going to run a 90 amp circuit, why not run a 100 amp circuit and take full advantage of the car's twin chargers (just like the HPWC would).

Doug can probably answer this better than I could. First, I'm not sure if the CS-100 is available yet since Sun Country doesn't show pricing for it.
Second, Tesla's web site says that a public J1772 charger can deliver 80Amps. I thought the J1772 design standard was limited to less ampacity than the Model S can handle. My understanding of the Sun Country product line is that you would have to use the J1772 adapter to charge the car, so does that mean that the charger can output 90 Amps but that only 80 Amps would reach the car or can the full 90 Amps go through the J1772 connection?

Continuous current from a 100 amp EVSE is 80 amps, whether it's Sun Country's or Tesla's. That's an electrical code thing. The CS-90 would deliver about 70 amps continuous.

I find it rather frustrating - and not a little surprising - that you should choose to call your products 'chargers' when they are nothing of the sort! Your products are all EVSEs (electric vehicle service equipments. 'Charge(ing) Point' or Charge(ing) Station' are also good. All they do is safely provide a means of connecting an EVs real charger(s) to an electricity supply and switching the power on and off - in the same way that a simple switched AC mains receptacle (socket) does - albeit at much higher power levels.

Calling them 'chargers' is not only technically incorrect but also confuses the Hell out of everyone, particularly EV newbies. They will (rightly) wonder why, if your EVChargers are chargers, do they need another charger in the car?! I guess it is too late to change their name into something less confusing and more intelligent but you might like to consider it none the less.

Martin, whilst technically correct, in common parlance here in North America, "charging point", or charging station" has been abbreviated (rightly or wrongly) to "charger"...EVSE is too cumbersome and often times requires further explanation...
